Find Python engineers shipping Data science
The list above ranks the most-starred public Python repositories tagged with the Data science topic, drawn from the public GitHub graph. Across 1,211 matching repositories, the contributors are a tight cluster of engineers with both Python chops and real Data science experience.
That overlap is rare. Most Python engineers haven’t shipped Data science, and most Data science maintainers don’t write Python. The people on this list’s contributor graph are the ones who do both.
Refolk turns this list into a search. Ask for “Python Data science maintainers hiring” or “Python engineers shipping Data science in 2025” and Refolk returns a ranked shortlist with the commits, profiles, and projects behind each name.

Common questions
How are these repositories ranked?
By stars, with forks and recent activity as tiebreakers, read from the public GitHub API. The methodology section above has the details.
How fresh is the data?
The ranking re-renders at least daily. Last refreshed: Sun, 20 Sep 2026 10:50:00 GMT.
Can I find the maintainers and contributors behind these repos?
Yes. Stars rank the projects; I can rank the engineers - maintainers, top contributors, and the people they work with. You start with 500 free credits, no card required.
Can I use this list for hiring?
That's the point. I read hiring signals across GitHub, LinkedIn, and the open web, so a repo list turns into a shortlist of engineers worth talking to.
Try it on the search you came here for
Stop building boolean strings. Just describe the person.
Type one sentence. I plan the search, read GitHub, public LinkedIn and Crunchbase records, and the open web as it is right now, and hand back a ranked list with the reason next to every name.
01Describe them
One plain sentence. Role, city, stack, stage, whatever matters to you.
02I read the web live
GitHub, public LinkedIn and Crunchbase records, the open web. Not a database that went stale last quarter.
03You read the shortlist
Ranked, with the reasoning under every name. Open a profile, ask a follow-up, narrow it down.
- Staff backend engineers in NYC who shipped Rust in production
- Series A fintechs in SF under 50 people, growing headcount this year
- Maintainers of fast-growing Rust web frameworks on GitHub
- No boolean, no filters, no seat to buy. One box.
- Read at search time, so a profile updated yesterday counts today.
- Every step visible as it runs, every name with its reason.
